This is in no way an argument, but I want a more through answer to why I am finding Boost Enhancement Maps on a majority of EVO ROMs? I will agree that they are not related to Anti-Lag.
I apologize for not understanding the Anti-Lag silex was referring to, but I have little understanding on race concepts. I am only familiar with production vehicle ROMs pulled from EVOs and have practically memorized there structure, and map locations.
Evolutonm.net was awesome for the videos that showed what Anti-Lag is. How practical is this on a production car? Looks like something that would beat up a turbo quick.
My explanation was geared to “Turbo Lag”, and seemed to fit in principal with the data presented in the ROMs. All the ROMs I ever dealt with were production vehicles, limited by emissions regulation and reliability issues. I doubt Mitsubishi would implement the Anti-Lag system in its production cars for the wear and tear on the car even on EVOs (imagine a 3 month warranty).
Without splitting hairs on what ECU Flash calls “anti-lag” to define the tables, I would like to know what the data represents in the ROMs. Why educated engineers would put “dead” maps in ROMs and only certain models makes no sense. ROMs tend to be very particular to input and output systems of the vehicle.
Now with TURBO LAG in mind, when you lean the fuel at lower load it runs hotter combustion, this in turn creating more pressure and a bit more boost. This also being the safest range to run the engine with a 16.7 AFR, while there is a huge reduction in the risk of knock. This seems like something that can be used on all turbocharged production vehicles. Are these maps TURBO LAG related? LET ME KNOW.
This follows the data in the maps and is found in a majority of EVO 7, 8, and 9 ROMs.
Don’t believe me, download and look for yourself in HEX or DEC.
I have refused to put any XML updates to the EVOs that have these maps (about all), until I have some explanation on there principal to the data represented in the ROMs. If you would like to VIEW (not use) these XML defs to help find out how they function, PM me and I’ll send them (for address locations).
